IMPROVEMENT IN LUBRICATORS.

Specification forming part of Letters Patent No. 174,508, dated March 7, 1876; application filed A p I February 17, 1873.

- let and outlet passages, with a filtering-substance, and an adjustable screw-cap for compressing this substance; second, in the combination, with the elements of the tirstclause, of a shut-off valve, all of which will be fully described hereinafter.

In the drawings, Figure 1 representsa central vertical sectional elevation of my improved lubricator; Fig. 2, a plan view of the cover I, and Fig. 3, a separate view of the internal cylinder for regulating the supply of oil.

A represents the reservoir proper. resents the internal regulating-cylinder, provided with the orifices b bl and the screwthread extension b having the central orifice d, and the central internally threaded projection 0, having the lateral openings 0 c, as shown. G represents a screw-cap, adapted to close the upper part of the chamber B, and provided with a square tube, H, as shown. D represents a screw-valve, which is operated by means of the stem E, as shown, to open or close the central orifice d in the extension W, as shown in Fig. 1. K represents sponge or similar material interposed between the openings c and b, as shown in Fig. 1. L represents a cork collar, by means of which the glass and metal parts are united with a tight joint. M. represents an attachment, preferably of wood, by means of which the lubricator is adapted to be attached to the shafting.

The operation is as follows: The oil in the vessel A, when the lubricator is in operation, passes into the opening b through the sponge K and openings 0 into the passage 11, the plug D being raised for that purpose, and from thence to the shafting.

The sponge or other filling material may be more or less compressed by adjusting the cap G, as may bedesired. By raising it sufliciently high, also, the oil may be permitted to flow in through the openings 1).

The sponge serves to filter the oil and retain all sand and grit which may be contained therein. At night, or when the machinery is at rest, the flow of oil may be cut 011' by screw ing down the plug D.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of thecylinderB,having passages b b d, with the filtering substance K and the adjusting-cap G, as described.

2. The combination of the cylinder B, havingopenings 12 b d, and threaded extensions b with a cap, G, and valve D, as described.
